Abstract: Systems, devices, and methods for delivering laser energy to a target in an endoscopic procedure are disclosed. An exemplary method comprises providing a first laser pulse train and a different second laser pulse train emitting from a distal end of an endoscope and incident on a target. The first laser pulse train has a first laser energy level, and the second laser pulse train has a second laser energy level higher than the first laser energy level. In an example, the first laser pulse train is used to form cracks on a surface of a calculi structure, and the second laser pulse train causes fragmentation of the calculi structure after the cracks are formed.

Abstract: Systems, devices, and methods for endoscopic mapping of a target and tracking of endoscope locations inside a subject's body during a procedure are disclosed. An exemplary system comprises an imaging system configured to capture an endoscopic image of the target that includes a footprint of an aiming beam directed at the target, and a video processor configured to identifying one or more landmarks from the captured endoscopic image and determine their respective locations relative to the aiming beam footprint, and generate a target map by integrating a plurality of endoscopic images based on landmarks identified from one or more of the plurality of endoscopic images. The target map can be used to track endoscope location during an endoscopic procedure.

Abstract: A probe of a target identification system can be extended via a first lumen of a viewing instrument, such as for illuminating an area beyond a distal end of the viewing instrument via an optical path of the viewing instrument. An optical response to the illumination of the area can be received via an optical path of the probe and can be split from other optical signals of the optical path. The optical response information can be used to identify characteristics of a target and to adjust parameters of a working instrument such as a working instrument contemporaneously using the probe.

Abstract: Systems, devices, and methods for identifying a target during an endoscopic procedure are disclosed. An endoscopic target identification system includes an endoscope having an endoscopic illumination source, an optical fiber insertable through a working channel of the endoscope and coupled to a non-endoscopic illumination source different from the endoscopic illumination source, and a controller. The controller can send a control signal to the non-endoscopic illumination source to emit a diagnostic beam through the optical fiber when the at least one endoscopic illumination source changes from a first mode to a second mode. The second mode has a lower amount of illumination than the first mode. The controller can determine a composition of a target based on the diagnostic beam incident on the target and light from the diagnostic beam being reflected from the target.

Abstract: A device for performing a surgical procedure can comprise a shaft extending from a proximal portion to a distal portion, a light conductor extending at least partially through the shaft to be exposed at the distal portion, and a damage mitigator positioned to receive light from the light conductor to discharge the light from the device. A method of preventing damage to an optical fiber in a medical device having laser treatment capabilities can comprise emitting a laser beam from the optical fiber, fragmenting a biological stone with the laser beam, and mitigating damage to the optical fiber from fragmentation of the biological stone.

Abstract: A system for spectroscopic signal detection can comprise a spectrometer, a light source emitter configurable to emit a first signal toward a target, and an aiming light source emitter configurable to emit a second signal having a visible spectrum toward the target. The system can include a first optical component such as a filter for attenuating or removing noise associated with the second signal from a third signal from the target back to the spectrometer.

Abstract: A laser can be controlled based on different tissue compositions, such as in real time. After a first time period, a first composition of a in vivo target site can be identified. Based on the first composition, a plurality of lasers can be controlled to emit light at a first wavelength where controlling includes activating a first combination of the plurality of lasers. After a second time period, a second composition of the in vivo target site different from the first composition can be identified. Based on the second composition, a plurality of lasers can be controlled to emit light at a second wavelength, such as can include activating a second combination of the plurality of lasers. The first combination of the plurality of lasers can be different from the second combination of the plurality of lasers.
